Induction motor rotor slot shape

May 20, 2017 · In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages. This is called Effects of the Geometry of the Rotor Slots on the magnitude whenthe motor possesses different geometrical rotor-slot shapes.The cross sectional areas of two typical semi-closedslotshapes (rectangular andro undshapes) are kept equally constant according to the IEEE induction motors, Proc. the 24th IASTED International Conference on Modelling, Identification, andControl (MIC 2005), Austria,

Three Phase Induction Motor Design in Windows Programming Platform ... the number of conductors per slot are found. The size and shape of the conductor is decided depending on the power rating. The stator winding and ... motors. For deep bar rotor, it is in the range of 5.5 to 7.5 A/ mm2 . The snapshots of rotor design module are given in Fig US8344581B2 - Induction motor rotor core having shaped ... To provide an indication motor rotor capable of improving motor performance by concentrating portions under magnetic saturation conditions of rotor teeth. The rotor of an induction motor of this invention may include slots formed approximately in the shape of a T. The slots may be formed so that top slots are arranged on an outer peripheral portion of a rotor core, and bottom slots are ... Wound Rotor - TECO-Westinghouse motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build-up generated during motor start-up. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances.

Figure 4-8.—Induction motor.Regardless of the type of rotor used, the basic principle is the same. The rotating magnetic field generated in the stator induces a magnetic field in the rotor. Rotor EMF, Current and Power in Induction Motors… In an induction motor, when the number of stator slots is equal to an integral multiple of rotor slots.If a 400 V, 50 hz star connected, 3-phase squirrel cage induction motor is operated from 400V and 75 Hz supply. The torque that the motor can now provide while drawing rated current from... Rotor Slot Distance Effects on Output Parameters in Single… In this paper, single phase induction motor which has different rotor slot distances are analyzed with 2-D Finite Element Method (FEM). The analyses are carried out using ANSYS/Maxwell program which solves equations with FEM. The model has same stator and rotor slot geometry.

The impact of the rotor slot number selection on the induction motors is investigated. Firstly, analytical equations will reveal the spatial harmonic index of the air gap magnetic flux density, connected to the geometrical features and the saturation of the induction motor.

Construction of Induction Motor The three phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable.

Three Phase Induction Motors | Special Designs | Torque Motor Three Phase Induction Motors:. Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two ends while in wound-rotor motor, the rotor also has a balanced three-phase distributed winding having same poles as stator winding. 3-Phase Induction Motors • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The rotor will constantly be turning to align its magnetic field with that of the stator field. • The 3-phase set of currents, each of equal magnitude and with a phase
